Exasperated, she gestures with her hand towards the Italian PM and asks 'What is it? Why does he have to shout?'

Another comment said: 'It's what the world has come to expect from
Silvio - and he now wants to be President of Italy. God help us.'

As well as being popular on the web, the Queen's disapproval of
Berlusconi was seized upon by newspapers back in Italy who put the
story on their front pages.

Corriere Della Sera had a cartoon on its front page showing the
Queen with her fingers in her ears and the other G20 leaders looking
startled as Berlusconi shouted out. The caption read:'The Voice of
Italy'.

German MEP Martin Schulz who Berlusconi referred to as a 'concentration camp guard'

Corriere Della Sera's editorial described Wednesday's incident as an 'embarrassment' for Italy.

Meanwhile, another cartoon in La Repubblica shows two people discussing
the incident with one saying:'Berlusconi's capacity for making a
spectacle is unreachable.'

The other replies: 'Here in Italy we call it charisma.'

Its article read: 'Yesterday on the web there was nothing more
clicked, nothing more talked of and it had nothing to do with
international politics.'

At a photoshoot of world leaders at the G20 meeting in London yesterday Berlusconi managed to get noticed by not appearing in it.

First the Canadian PM disappeared for a 'bathroom break' and by the time he was back Berlusconi had disappeared.

Mr Berlusconi, 72, is well known for his gaffes and schoolboy jokes on the world's stage.

He has also caused outrage by referring to German MEP Martin Schulz as a 'concentration camp guard'.

At the start of Italy's EU presidency in July 2003 he said: 'I know
that in Italy there is a man producing a film on Nazi concentration
camps - I shall put you forward for the role of Kapo (guard chosen from
among the prisoners) - you would be perfect.'

He offended the Chinese in 2006 at a rally during the 2006 election
campaign by saying: 'Read The Black Book of Communism and you will
discover that in the China of Mao, they did not eat children, but had
them boiled to fertilise the fields.'

And while at the New York stock exchange he managed the following
comment: 'Italy is now a great country to invest in... today we have
fewer communists and those who are still there deny having been one.
Another reason to invest in Italy is that we have beautiful
secretaries... superb girls.'

And Mr Berlusconi boasted that he had used all his 'playboy charms'
to win over Finland's female prime minister to convince her to set up
the EU Food Safety Authority in Parma, Italy.

His practical jokes have also fallen foul of his long suffering wife
Veronica - he was forced to make a public apology to her after he told
two stunning TV starlets that he 'would marry them' if he wasn't
already married.

Fabio Evangelisti, of Italy's anti sleaze party Italia dei Valori
(Italy of Values), said: 'At the G20, Italy has made its umpteenth
embarrassing international impression.

'Our country does not deserve a Prime Minister who shouts out and
earns the rebuke of the Queen - he can behave like that when he is with
his songwriting friend [Mariano] Apicella or with his TV friends.

'He should not behave like that when he is representing Italy. It is
not right that he should discredit our image in the world in this way.'

Where's Silvio? In the top picture, Canadian PM Stephen Harper is missing after taking a 'bathroom break'. The gap is clearly visible on the middle right. But Berlusconi can be seen in the back row behind Obama. However moments later the Canadian PM is back but Berlusconi has gone AWOL
